No Booze (April Fool's Day - 1923)

San Jose hat dealer Jay McCabe posted a sign in his window announcing that a truckload of booze had fallen into the Coyote creek at the Julian Street bridge, and that the driver had fled. Scores of people drove to the location, found no truck, and then remembered what day it was.

(This was during the Prohibition Era, so a truckload of booze would have been a particularly tempting attraction.)
